My invention relates to a slicing machine and particularly to a slicing machinein which is employed a rotary knife, which may be motor driven, with which is used a'work support guided for movement across .the face and past the cutting edge of the knife. One object Vof my invention isV to provide improved means for adjusting the angle of said work support. Other objects will appear from time to time in the course of the specification and claims.

I -illustrate my invention more or less diagrammatically in the accompanying drawings, wherein-f Figure lis a front elevation;

Figure 2 is a side .elevation with parts broken away;

Figure 3 is a front elevation of a variant form; j Y

Figure fl is a side 'elevation of a variant form; and

Figure 'is apartial plan view. A

Like parts are indicated by like symbols throughout the specification and drawings.

Referring first to the form of Figures l and 2, A generally indicates any suitable base or Vframe member mountedV on supports A1. Mounted on the base A is any suitable motor or transmission means, not herein shown,

whereby the circular knife B is rotated. I indicate inassociation with said knife the knifeshaft B1 and the pulley B2 about which passes the driving` belt B3.

C generally indicates a guard pla-te for the front of the knife, the arcuate edge C1 of the guard plate penetrating the frontrecess B4 in the knife. c

D generally indicates a gauge plate structure which may be moved, in any suitable manner, toward and away from the cutting' plane'in order to adjust the thickness of the slices.- f

E generally indicates av Work supporting carriage `mounted for example on the track El. It is provided with a depending portion E2 in guiding relationship with the track E3. A certain adjustmentof the position of the carriage is ossible, about the rail El, by adjustment of hescrew threaded elements E3, which engage each side of the track E3.

-gations E, herein shown as formed by intersecting plane surfaces E7. The table E3 is apertured or slotted as at E3, for a purpose which will later appear. V

G generally indicates the work support with a main supporting surface G1 and an abutment iange G2, herein shown as at right angles thereto, positioned along the edge which ,is most: remote from the cuttingfedge of the knife at the initiation of the cutting stroke It is upwardly extended as at G3, adjacent the cutting edge of the knife. IThe portion G3 is herein shown as connected, as by the curved link G4, with the tablel?5 of the carriage. The link G4 is pivoted as at G5 and G3. G7 indicates a projection adjacent the kintersection of the members .G1 and G3, which is adapted `to seat in the corrugations E3 as shown in Figure 1. G3 indicates a spring, anchored as at G3 on the carriage struct-ure, with its opposite end secured as atv G13, :to

the bottom of the member G. The aperture 1 E3 is of sufficient size to permit the spring to pass therethrough, as when it is in the dotted line position in Figure l. A

I provide a pusher plate, generally indi cated as H, slidable on the member lG and away from the cutting plane. The plate H may be connected, as by the handle H1 and its lateral extension H2, to the bearing sleeve H3. Said bearing sleeve in turn is slidable along the guiding pin H4 which may be mounted asat H5 on the upward extension G3 of the flange G2.' It will be. clear-from Figure 1 that the vlink G4 is so formed as not to contact `the sleeve VH3 at any normalV position thereof. j l j f' Referring to the form of Figures 3 'to f5 inclusiveI illust-rate the carriage J provided lvu with a semi-cylindrical or partially cylindrical bearing portion J1, which is shown as having its inner and otherwise cylindrical surface knurled or roughened as at J 2. This member J1 is provided with one or more apertures J 3.

Rota-table in relation to the member J 1 is the cylindrical or partially cylindrical member K the surface of which is-roughened as at K1. Associated with it are the locking screws K2 which pass through the apertures J 3. K3 are locking members, indicated as wing nuts, whereby the two members can be locked together to prevent their relative rotation.

j Associated with the member K is the work support proper which includes the mainf work supporting member L with an abutment flange L1 upwardly projecting from that edge thereof which is most remote from the cutting edge of the knife at the initiation of the cutting excursion. In the form indicated in Fig. 3 the members L and L1 are connected to the member K .along their abutting edgesQ M generally indicates a pusher plate with it-s handle M1 connected as by the member M2 with the bearing sleeve M3 slidable along the guiding pin M1 which is secured as at M5 tothe member L1. Y

It will be realized that whereas I have described and shown a practical and operative device, nevertheless many changes might be made in the size, shape, number and disposition of parts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to my specific showing.

The use and operation of my invention are as follows:

In slicing machines of the type herein described itis desirable to have a work support, movable with the carriage across the face of the knife, which support is adjustable in rela- .tionto the carriage.

Some articles, such as bread, bacon and the like are best sliced when resting upon a broad horizontal surface such as that of the member G1, or L. Vhen the meat support is tilted in the position in which it is shown in dotted line in Figure 3, or in dotted line in Figure l, the space is insuflicient to receive a piece of bacon for de-rinding or a piece of bread for de-crusting. The length of the bacon or of the bread loaf is -such that if it is positioned on the carriage when the carriage is in the tilted position, the

Vupper portion of the bacon or bread engages the cover member lD1" and cannot be moved into cutting engagement with theV knife.

On the other hand, as when cutting small articles or more or less soft articles such as sausage, it is advantageous to employ a trough which is V-shaped incross-section, a trough such as is provided by the work support when it is in the tilted position, as shown in Figures l and 8. I obtain both results by providing a work support which may, at the election of the operator, be positioned in horizontal position or in inclined position. Referring to the form of Figures 1 and 2, the work support may normally be in the full line position. When in suoli position the member G7 penetrates the groove or channel E6 farthest to the left, referring to the parts in the position in which they are shown in Figure l. The spring G8 holds the work support clamped downwardly in the position in which it is shown in full line. When Vit is desired to tilt the work support it is simply lifted against the'spring Gs and the member G7 is dropped intoV the desired groove or notch E6. The spring still serves to hold the parts locked in position, exerting tension upon the link G4.

In the form shown in Figures 3 and following a similar adjustment is obtained by merely loosening the wing nuts K2 and rotating the cylindrical member K. This member may be of any desired radius and its center of rotation need not, as shown in Figure 3, conform to the corner or intersection of the members L L1. lVhereas I have illustrated the form in which two locking members are employed it will be realized that any desired number, two or more than two, can be employed. Two, however, is a convenient number and lends itself to the central location of the track E1 in relation to the carriage J.

The characteristic application of my invention is generally stated as the employment of a direct locking connection between the work support and the carriage. For eX- ample in the form of Figures l and following the work support actually engages some one or another of the channels or grooves Ee in the face of the carriage and the only locking means necessary are the means, for example the spring G8, for preventing movement of the abutting portions of work support and carriage. Similarly in the form of Figures 3 and following, the cylindrical abutment portion K, directly connected to the work support, is roughened for a direct locking engagement with the opposed concave abutment portion of the carriage. The function of the locking means, namely the screws and wing nuts shown for example in, Figure 3, is to maintain this direct locking engagement between the opposed or abutting portions of work support and carriage'. Adjustment of the carriage J about the rail E1 is made possible by the adjusting screws J threaded in the depending portion J 6 which engage the track E3.
